The hamadryas baboon is one primate species that fails the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. as an attempt to determine whether an animal possesses the ability of visual self-recognition.

The best known research technique in this area is the mirror test devised by Gordon G. Gallup, in which an animal's skin is marked in some way while it is asleep or sedated, and it is then allowed to see its reflection in a mirror; if the animal spontaneously directs grooming behavior towards the mark, that is taken as an indication that it is ...
Although many animals respond to a mirror, very few show any evidence that they recognize it is in fact themselves in the mirror reflection. The Asian elephants in the study also displayed this type of behavior when standing in front of a 2.5-by-2.5-metre (8.2 ft × 8.2 ft) mirror – they inspected the mirror and brought food close to the ...
Animal reflectors or mirrors are important to the survival of many kinds of animal, and, in some cases, have been mimicked by engineers developing photonic crystals. Examples are the scales of silvery fish, and the tapetum lucidum that causes the eyeshine of dogs and cats. All these reflectors work by interference of light in multilayer ...
Macroscopic examples of chirality are found in the plant kingdom, the animal kingdom and all other groups of organisms. A simple example is the coiling direction of any climber plant, which can grow to form either a left- or right-handed helix. In anatomy, chirality is found in the imperfect mirror image symmetry of many kinds of animal bodies.

How quickly can you solve it? Play now! In the comments section, others reacted to the video, with one stating, “This is the best we listen and we don’t judge I’ve seen 😂."
It should not be surprising then that his visual imagery for object size, shape, and color is intact. For example, when shown a picture of an animal, he can correctly answer questions such as "are the ears up or down?" and "is the tail long or short?" He can correctly identify colors, for example that the inside of a cantaloupe is orange. [19]
